Since PPOs make their revenues off access fees with absolutely no responsibility to screen claims for accuracy and since their market value is directly tied to the number of physicians and facilities they have inside their networks, employers and their administrative payers’ demands for transparency have gone unmet over the last decade. This has led to the significant movement to eliminate PPO arrangements altogether as they not only provide no real value to the healthcare equation but in many cases promote a negative value. This is the efficient market theory at work, all elements within a market that do not add value to the overall market will eventually be eliminated.
